link: Who Has Two Thumbs And Is Ready For A "Cloaking" Device?

Researchers have “cloaked” a three-dimensional object, making it invisible from all angles, for the first time.

Most of the high-profile invisibility cloaking efforts have focused on the engineering of “metamaterials” - modifying materials to have properties that cannot be found in nature.
The modifications allow metamaterials to guide and channel light in unusual ways - specifically, to make the light rays arrive as if they had not passed over or been reflected by a cloaked object.
